You're stepping into a conversation that is four years - or more - in the making. My beef isn't with Mahomes; he is truly great, there's no question about that. But he's not the GOAT, which is what many people have been saying for well before he even won his second. My beef is with the way people have to anoint the next greatest before they have even achieved great, and with how we have to tear down those that ARE the GOAT in order to justify "our opinion". Mahomes IS great; he's not in the top three GOATS, though, not yet. When he does a complete iteration of all his supporting cast and THEN achieves what he did - which is what Brady did, TWICE - then he's in the conversation.
But again, you're watching a TV show and tuned in 41 minutes after the hour; Dream Team has been taking every opportunity to denigrate and downplay Brady (often but not always in favor of Mahomes) for years now.
